MCQ IN MEDICINE

Detailed explanation-1: -When the air is super cold, it will take away your body heat, leaving you feeling – you guessed it – cold! As part of the process of homeostasis, shivering is one way that your body tries to produce more warmth and make up for all the heat it’s losing to the cold air.

Detailed explanation-2: -Shivering is muscle activity that generates heat and warms the body. Similarly, some insects vibrate their wings for a while before flight, heating the muscles to the temperature at which they work best. When an animal shivers in the cold, a large amount of heat is generated in the muscles.

Detailed explanation-3: -When exposed to cold temperatures, your body begins to lose heat faster than it is produced. Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature.

Detailed explanation-4: -As the environment warms-up, the body tends to warm-up as well. The body’s internal “thermostat” maintains a constant inner body temperature by pumping more blood to the skin and by increasing sweat production. In this way, the body increases the rate of heat loss to balance the heat burden.
